Adaptive bidding for networked advertising

ABSTRACT

An adaptive bidder for networked advertising. A bid request is received from an exchange over a network. Each bid request represents the opportunity to bid on an advertising opportunity. A processing time limit is determined based at least in part on a network latency measurement, an exchange reported timeout and a bid response buffer. The network latency measurement may be required to meet a freshness standard. The bid response buffer represents the time allotted for the adaptive bidding system to generate a response based on one or more partial results. The exchange reported timeout value can be included in the bid request, and can vary from bid request to bid request. The execution of one or more tasks is initiated by the adaptive bidding system, and each task can make a partial result available. In some cases, a partial result is a cumulative result. A response is determined from one or more partial results which are available before the processing time limit expires. The response is provided to the exchange.

BACKGROUND Field of Invention

The invention relates to selecting bid prices for submission to onlineadvertising exchanges under variable conditions.

Description of Related Art

Online advertising opportunities are bought and sold through variousexchanges such as Real Time Bidding (RTB) exchanges and onlineadvertising auction systems. For example, an exchange may provide astream of bid requests, or “call-outs” to a bidder, with each bidrequest describing an advertising opportunity available for bidding.Typically, an exchange notifies bidders of a minimum time-to-respond.Increasingly, bidders are utilizing sophisticated analyses to determinewhich advertising opportunities are of interest and how much to bid onthem. Many bidders may not be capable of responding to all of the bidopportunities available through an exchange within the limited timewindow. Furthermore, the responses which are sent can be subject tovariable network delays, resulting in bid responses which arrive at theexchange too late for consideration. Some exchanges may reduce thevolume of “call-outs” provided to a bidder with a poor response rate.

What is needed is a way for auction participants to take advantage ofthe available processing time window, which can be variable, andreliably provide timely responses.

SUMMARY

Embodiments of the invention provide a method, a non-transitorycomputer-readable storage medium and a system for adaptive bidding fornetworked advertising. In an embodiment, a bid request is received froman exchange over a network at an adaptive bidding system. A bid requestis a request to bid on an advertising opportunity. The adaptive biddingsystem determines a processing time limit for the bid request, based atleast in part on a network latency measurement and the exchange reportedtimeout value. The processing time limit also includes a bufferallotting time to generate a response from one or more partial results.In some cases, the bid request can include the exchange reported timeoutvalue, which is not necessarily the same for all bid requests. Theadaptive bidding system initiates one or more tasks for bid requestanalysis. A task can generate one or more partial results, which aremade available for additional processing. A response to the bid requestis determined from one or more partial results which are availablebefore the processing time limit expires. The response is provided tothe exchange over the network. Advantageously, the adaptive biddingsystem can adaptively take advantage of longer processing times whennetwork latency is low or exchange reported timeouts are long, andreduce the likelihood of tardy responses when network latency is high orexchange reported timeouts are short.

In some embodiments, the adaptive bidding system can provide theprocessing time limit to a task manager, which may select a set of tasksfor execution based on the processing time limit.

In some embodiments, the adaptive bidding system can provide theprocessing time limit to a task manager, which may prioritize a set oftasks for execution based on the processing time limit.

Advantageously, in an embodiment, realistic estimation of the availableprocessing time for responding to a bid request in conjunction with aflexible bid analysis process enables the adaptive bidding system toefficiently analyze each bid request, while still remaining responsiveto an online exchange.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates an example computing environment in accordance withan embodiment. As shown in FIG. 1, the computing environment includes anadaptive bidding system 100, a content provider 110, at least one entity120, a direct measurement system 130, an exchange system 140 and acampaign operations system 150. These elements are connected by acommunication network 160, such as a local area network, a wide areanetwork, a wireless network, an intranet, a cable network, a satellitenetwork, a cellular phone network, an optical network, the Internet orcombinations thereof.

Content provider 110 provides content 111 over the communication network160 to entity 120. Examples of a content provider 110 can include website operators and cable television operators. Examples of content 111can include, but are not limited to, a webpage, a portion of an onlinevideo clip, a portion of a networked television program, a portion of acable television program, a portion of a satellite television program, aportion of an Internet Protocol (IP) television program, a portion of anonline audio clip, the results of a keyword search from an online searchengine, the results of a request for directions from an online mappingservice, advertising content and interfaces for making online purchases.

Content can be identified using a content descriptor, such as, but notlimited to, a name, a filename, an identifier, an IP address, a networkaddress, a URL, a domain name, a hostname or combinations thereof.Content descriptors may or may not be unique. For example, websitecontent can change as websites are updated over time; a contentdescriptor such as a URL without an associated time and date stamp canbe non-unique. In another example, aggregate content such as thecollection of webpages accessible through a website, can be identifiedwith a single content descriptor, such as a domain name. In someexamples, the content 111 can be provided based on a request to thecontent provider 110; in some examples, the content provider 110 canpush the content 111. Although only one content provider 110 is shown inFIG. 1 for clarity, any number of content providers may be connected tothe communication network 160.

In various embodiments, entity 120 accesses content 111 from contentprovider 110 over the communication network 160. Examples of entitiescan include consumers, software installations or hardware devices usedto access content or combinations thereof. A consumer is a person orgroup of people who access content. Software installations can include aweb browser instance, video viewer instance or set-top box softwareresiding on a hardware device. A hardware device can comprise acomputer, personal digital assistant (PDA), cell phone or set-top unit(STU) such as a STU used in conjunction with cable television service.In some cases, an entity 120 can comprise a combination of entitieswhich are logically grouped together to represent individuals,households or groups of individuals who access content 111. Althoughonly one entity 120 is shown in FIG. 1 for clarity, any number ofentities may be connected to the communication network 160.

As shown in the embodiment of FIG. 1, an identifier 121 is stored inentity 120. For example, a hardware device identifier such as a MediaAccess Control Address (MAC address) can be stored on a device. Asoftware identifier such as a cookie value can be stored locally. Inanother embodiment, identifiers can be partially or wholly composedand/or stored remotely from an entity. In an example, identifiers do notcomprise personally identifiable information (PII) such as a person'sname or street address.

An advertising exchange, such as exchange system 140, is an electronicmarketplace for buying and selling advertising impressions, such as theopportunity to expose an entity to advertising content delivered over anetwork. In an example, a real time bidding (RTB) advertising exchangecan support the rapid auction of advertising opportunities as theybecome available. For example, the exchange 140 can be notified by acontent provider after an entity requests content from the contentprovider and an opportunity to provide an advertising impression to thatentity becomes available. The exchange 140 can provide a stream of bidrequests to a bidder, with each bid request representing a request tobid on an advertising opportunity with an intended recipient. Examplesof exchanges include first price auction systems and second priceauction systems.

A bid request can comprise information related to an advertisingopportunity available for bid. For example, the exchange may provideadvertising opportunity characteristics in a bid request which describethe advertising impression opportunity, such as the size of theadvertising impression, the position of the advertising impression withrespect to a web page, the website location of the advertisingimpression, the context or topic of the display webpage associated withthe advertising impression or combinations thereof.

In some cases, the exchange may provide information in the bid request,such as details related to the entity representing the intendedrecipient of the advertising impression such as, but not limited to, thelocal time of day for that entity, the entity's media market in the formof a Designated Market Area (DMA), an entity identifier or combinationsthereof.

Some exchange systems enable auction participants to set or retrieve anentity identifier, such as a browser cookie, with the entity which isthe intended recipient of the advertising opportunity's advertisingimpression. For example, this can enable the auction participants tomaintain or access a partial media consumption history with respect toan entity. In some cases, the adaptive bidding system can be integratedwith a direct measurement system 130 or other systems which can takeadvantage of this feature, enabling the adaptive bidding system toaccess collected, measured or inferred advertising opportunitycharacteristics stored in a variety of systems which may be internal orexternal to the adaptive bidding system.

An exchange reported timeout value describes the amount of time thebidders have to provide a response to a bid request. The exchangereported timeout value can be measured from the time the exchange issuesthe bid request to the time the exchange receives the response to thebid request; however, the exchange can use other time origins toinitiate the countdown for the exchange reported timeout and/or otherendpoints to determine compliance with an exchange reported timeout.Responses from bidders returned to the exchange within the exchangereported timeout value can be considered by the exchange. In some cases,an exchange may provide an exchange reported timeout value, applicableto some or all bid requests. In some cases, exchange reported timeoutvalues may be provided in conjunction with each bid request. An exchangesystem 140 receives responses to the bid request which can include a bidprice, selects the winning bid and enables the winning bidder to sendthe advertising content to the entity 120. In some cases, an advertisingserver system (not shown) may be integrated into the process, and theadvertising content may be served to the entity 120 by the advertisingserver system on behalf of the winning bidder.

Some exchange systems monitor the responsiveness of bidders, and maytake undesirable actions with respect to bidders which are notconsistently responsive. For example, an exchange may choose to throttlebid requests provided to some bidders. To avoid undesirable actions, abidder can provide a timely response including a “decline to bid”message to the exchange system, which may be considered responsive tothe bid request by some exchange systems. Although only one exchangesystem 140 is shown in FIG. 1 for clarity, any number of exchangesystems may be connected to the communications network 160.

A direct measurement system, such as direct measurement system 130 cancollect information for an entity 120. Direct measurement system 130includes a data repository 131, which is a data store such as adatabase, for storing information. Information can include a consumptionhistory for an entity 120 and attribute values. For example, aconsumption history can document one or more media consumption events. Amedia consumption event records the act of accessing content 111 over anetwork 160 by an entity 120, such as, but not limited to, an entityaccessing a web page from a web server. In some cases, media consumptionevents can comprise conversion events. In an example, a contentdescriptor for identifying the content 111 can become part of theconsumption history. In some cases, additional information such as thereferring webpage and search terms used to locate the content can becollected by the direct measurement system 130. In the embodimentillustrated in FIG. 1, direct measurement system 130 is external to theadaptive bidding system 100. However, in other embodiments, one or moredirect measurement systems may be internal to the adaptive biddingsystem 100 instead of or in addition to one or more external directmeasurement systems.

In some cases, a direct measurement system 130 can collect informationin conjunction with an identifier. For example, information can becollected in conjunction with an identifier in order to maintain acoherent body of information for an entity comprising a consumptionhistory and information. The identifier can comprise an identifier suchas identifier 121 stored on the entity and/or an identifier storedand/or composed remotely from the entity.

In an example, the information collected in conjunction with theconsumption history can comprise attribute values. For example,attribute values can comprise known, collected, received,cross-referenced, inferred, estimated, processed or calculatedinformation related to an entity 120 which is not part of a consumptionhistory. The estimated household size associated with an entity 120 andthe average household income for the zip code associated with an entity120 are examples of attribute values. In some cases, attribute valuescan be assessed or described using probabilities. For example, anattribute value can reflect that there is a 90% chance that thehousehold income for a family group owning an entity earns between$75,000 and $100,000 per year. In some cases, information can bereceived and processed into a processed attribute value. For example,attribute values can comprise information which has been statisticallyobfuscated to address privacy concerns.

In an example, the context of a consumption event, such as the qualityof the consumption event, can be part of the consumption history. Forexample, information associated with the hardware and software volumesettings during the delivery of an audio advertisement can be collected.For an entity that is a physical device, other information can describea hardware or software configuration and can be included in theconsumption history.

A campaign operations system 150 can participate in the onlineadvertising market by operating a networked advertising campaign. In anexample, a campaign operations system 150 can operate a networkedadvertising campaign by automatically purchasing advertising impressionsor authorizing the purchase of advertising impressions, and enablingtheir consumption. The advertising impressions can be purchased throughone or more systems such as exchange system 140. In some cases, acampaign operation system may use a model, such as a behavioral model,to assess the suitability of an advertising impressions for one or morecampaigns, to determine a bid price or both.

In an example, the exchange system 140 can be a Real Time Bidding (RTB)advertising exchange and the advertising impressions may be purchasedthrough an auction. A campaign operations system can receive informationabout an available advertising impression and then determine whichadvertising impressions are a good match, how much to bid on anadvertising impression, which advertising creative to use, customizationof an advertising creative or combinations thereof. The campaignoperation system can integrate with external systems, such asadvertising server system, to enable the consumption of an advertisingopportunity won in an auction. In some cases, a campaign operationssystem operates a single networked advertising campaign, but in otherexamples, a single campaign operation system may be configured tooperate multiple networked advertising campaigns for multipleadvertisers.

In an example embodiment of the invention, adaptive bidding system 100includes a network latency module 102 for determining a processing timelimit for a bid request, a task manager 104 for initiating tasks relatedto bid request analysis, a response constructor 106 for constructing aresponse to a bid request based on one or more partial responses and adata repository 108.

Adaptive bidding system 100 receives bid requests over a network fromone or more exchanges, with each bid request representing a request tobid on an advertising opportunity. In some cases, a bid request caninclude an exchange reported timeout value indicating the maximum amountof time that the bid analysis has to return a response to the exchangefor consideration. In some cases, an exchange may make an exchangereported timeout value available through other communication channels,such as providing the exchange reported timeout value or a defaultexchange reported timeout value in documentation provided to thebidders. In some cases, the exchange reported timeout value can bestored in a data repository 108.

Network latency module 102 can determine the processing time limit basedat least in part on a network latency measurement, the applicableexchange reported timeout value and a bid response buffer to account forthe time allotted to generate a response based on one or more partialresults. A network latency measurement is used to predict the timerequired to compensate for the expected network latency related to thebidding process. For example, one part of the network latencycorresponds to the time required for the bid request to travel over thenetwork from the exchange to the adaptive bidding system and a secondpart of the network latency corresponds to the time required for theresponse to the bid request to travel from the adaptive bidding systemto the exchange. Some fluctuations in network latency are to be expectedbased on changing network traffic conditions. In addition, someexchanges may provide bid requests from various locations, networks andsub-networks over time, so the expected network latency can vary frombid request to bid request, even for bid requests originating from thesame exchange.

A network latency module 102 can rely on operating system measurementsof the network latency per network address, such as the round trip time.In some cases, measurements of network latency may be further processedinto parameters such as the exponential moving average of the round triptime. In some cases, the network latency module 102 can guess that a setof network addresses represent co-located exchange systems whichcommunicate over similar or identical network pathways incurring similarnetwork latency patterns. For example, in a TCP/IP implementation, anetwork latency measurement may be assessed based on measurements for anIP address range, and applicable to determining processing time limitsfor bid requests originating from the same IP address range.

To ensure accuracy, the network latency measurement may be subject to afreshness standard. For example, a freshness standard may require thatat least some portion of the network latency measurement has beenacquired within the last second or last minute. In some cases, this cancorrespond to taking a relevant network latency measurement for a roundtrip between two IP addresses or two IP address ranges within a timewindow specified by the freshness standard. For network latencymeasurements which are subject to further processing, such as networklatency measurements which are processed into parameters such as theexponential moving average of the round trip time, the freshnessstandard can require that the parameter be determined using at least onemeasurement taken within a time window specified by the freshnessstandard.

In some cases, network latency module 102 or other modules in adaptivebidding system 100 may account for time consumed with internalprocessing overhead, fluctuations in internal resource availability,fluctuations in network latency related to internal or external systemsor modules other than the exchange or other concerns when determiningthe processing time limit.

A task manager 104 can initiate the execution of one or more tasks forbid request analysis. A task can be executed on a system or module whichis internal to the adaptive bidding system, external to the adaptivebidding system or partially external to the adaptive bidding system. Atask can make a partial result available. Partial results which areavailable before the processing time limit expires can be consideredwhen the adaptive bidding system determines a response to a bid request.For example, a task can analyze a bid request, the media consumptionhistory of the entity representing the intended recipient of theadvertising impression or both to make a partial result available. Thepartial result may suggest a bid price, an advertising campaign,creative content, content customization or combinations thereof.

In some cases, the adaptive bidding system may rely partially or whollyon a campaign operations system to determine which advertisingimpressions are a good match, determine how much to bid on anadvertising impression, determine an advertising creative to use,customize an advertising creative or combinations thereof. The campaignoperation system can integrate with external systems, such asadvertising server system, to enable the consumption of an advertisingopportunity won in an auction. In some cases, a campaign operationssystem operates a single networked advertising campaign, but in otherexamples, a single campaign operation system may be configured tooperate multiple networked advertising campaigns for multipleadvertisers. In FIG. 1, the campaign operation system 150 is external tothe adaptive bidding system 100. However, in other embodiments, one ormore campaign operation system 150 can be internal to adaptive biddingsystem 100 in addition to or instead of one or more external campaignoperations systems.

In an embodiment, the task manager 104 can initiate one or more tasksfor bid request analysis. FIG. 2 illustrates an example list of taskswhich can be initiated by a task manager. Task manager 104 may identifya comprehensive list of all tasks available on the adaptive biddingsystem. In some cases, the task manager may assemble a list of taskswhich are applicable to the newly received bid request, excluding someor all inapplicable tasks. Task manager 104 may assess dependenciesbetween tasks to properly sequence or parallelize tasks. For example,“Task 5” in FIG. 2 is “Shoe Campaign: Adjust bid price according to shoecampaign seasonality model” and can only be executed after a proposedbid price has been determined as the partial result of Tasks 1-4.

In some cases, two or more tasks may leverage the same activity. Forexample, the media consumption history for the entity representing theintended recipient of the advertising impression may be retrieved once,but used by multiple tasks.

In an embodiment, the task manager 104 may prioritize or synchronizetasks for initiation. In some cases, tasks may be prioritized foroperation based on the predicted completion time for the tasks in lightof the network latency measurement, the exchange reported timeout or theprocessing time limit. In some cases, tasks may be prioritized based onthe features of the bid request, such as the topic, or the mediaconsumption history of the entity representing the intended recipient ofthe advertising impression.

In some cases, a partial result may be cumulative, so that a partialresult which is newly available supersedes an older partial result. Forexample, a newly available partial result, such as the result of Task 5“Adjust bid price according to shoe campaign seasonality model” may takeinto account older partial results such as the partial results from theexecution of Tasks 1-3.

An adaptive bidding system can have a minimum time budget whichrepresents the amount of time required to complete analysis of the bidrequest and generate a response. An adaptive bidding system may pursuevarious strategies for generating a response to a bid request with ashort processing time limit, such as a processing time limit that isclose to or less than the minimum time budget. For example, the adaptivebidding system can provide a response comprising a message acknowledgingthe receipt of the bid request and informing the exchange that theadaptive bidding system has declined to bid on the bid request. Inanother example, the adaptive bidding system can submit a minimal bid inresponse to the bid request on behalf of an advertiser running anunconstrained exposure campaign or for a public service announcement.

In some cases, the bid request may be assessed on behalf of multiplecampaigns or sub-campaigns and the adaptive bidding system 100 canprovide a response to a bid request on behalf of one campaign orsub-campaign. In an example, the presumed value of the advertisingexposure to a campaign can be assessed per campaign or sub-campaign andused by the adaptive bidding system 100 to select a campaign orsub-campaign per response. In some cases, the calculated bid price canreflect the presumed value of the advertising exposure to a campaign.However, in other cases, the calculated bid price and the presumed valueof the advertising exposure to a campaign may not be directly relatedand may be determined separately. In some cases, preferentiallyselecting or prioritizing tasks which tend to indicate campaigns whichassign high presumed values to advertising exposures, or skipping taskswhich tend to be related to campaigns which assign low presumed valuesto advertising exposures. In another example, the task manager may use atask weighting strategy when prioritizing tasks, preferentiallyweighting tasks associated with campaigns which are under-served toincrease their access to advertising opportunities.

Response constructor 106 constructs the response to the bid requestbased on one or more partial results before the processing time limithas elapsed, and provides the response to the exchange. The responseconstructor 106 can keep track of elapsed time to ensure that theresponse to the exchange is provided in a timely manner and provide aresponse to the exchange based on whatever partial results are availablein order to prevent a tardy response to the exchange.

The response to the bid request includes a bid price. In some cases, theadvertising creative or directions for acquiring the advertisingcreative are included in the response to the bid request. In some cases,additional information, such as information which may be used tocustomize the advertising creative can also be included in the responseto the bid request.

FIG. 3 is a high-level block diagram illustrating an example of acomputer for use as an adaptive bidding system 100, a content provider110, an entity 120, a direct measurement system 130, an exchange system140 and/or a campaign operations system 150 of FIG. 1. Illustrated are aprocessor 302 coupled to a bus 304. Also coupled to the bus 304 are amemory 306, a storage device 308, a keyboard 310, a graphics adapter312, a pointing device 314, and a network adapter 316. A display 318 iscoupled to the graphics adapter 312.

FIG. 3 is a processor 302 may be any general-purpose processor. Thestorage device 308 is, in one embodiment, a hard disk drive but can alsobe any other device capable of storing data, such as a writeable compactdisk (CD) or DVD, or a solid-state memory device. The memory 306 may be,for example, firmware, read-only memory (ROM), non-volatile randomaccess memory (NVRAM), and/or RAM, and holds instructions and data usedby the processor 302. The pointing device 314 may be a mouse, trackball, or other type of pointing device, and is used in combination withthe keyboard 310 to input data into the computer 300. The graphicsadapter 312 displays images and other information on the display 318.The network adapter 316 couples the computer 300 to the network (notshown). In one embodiment, the network is the Internet. The network canalso utilize dedicated or private communications links that are notnecessarily part of the Internet.

As is known in the art, the computer 300 is adapted to execute computerprogram modules. As used herein, the term “module” refers to computerprogram logic and/or data for providing the specified functionality. Amodule can be implemented in hardware, firmware, and/or software. In oneembodiment, the modules are stored on the storage device 308, loadedinto the memory 306, and executed by the processor 302. The computer 300is configured to perform the specific functions and operations byvarious modules, for example as detailed in FIG. 4, and thereby operatesas a particular computer under such program control. The types ofcomputers 300 utilized by the entities of FIG. 1 can vary depending uponthe embodiment and the processing power utilized by the entity.

FIG. 4 is a flow chart illustrating an example of a method 400 foradaptive bidding, according to an embodiment. Referring to Step 410, abid request is received at the adaptive bidding system 100. A bidrequest comprises a request to bid on an advertising opportunity. Insome cases, the bid request can include an exchange reported timeoutvalue. The bid request can also include advertising opportunitycharacteristics, such as the size of the advertising impression, theposition of the advertising impression with respect to a web page, thewebsite location of the advertising impression, the context or topic ofthe display webpage associated with the advertising impression orcombinations thereof.

Referring to Step 420, a processing time limit for the bid request isdetermined based at least in part on a network latency measurement, anexchange reported timeout value and a bid response buffer which accountsfor the time allotted to generate a response based on one or morepartial results. In some cases, the processing time limit can bedetermined in two or more steps. For example, a preliminary processingtime limit can be determined based on the network latency measurementand the exchange reported timeout value. Later, a bid response buffercan be allocated based on the expected number of partial results, andincluded in an updated processing time limit. In another example, theprocessing time limit may be updated based on a fresh network latencymeasurement or information related to the timing of processes internalor external to the adaptive bidding system.

Referring to Step 430, the execution of one or more tasks for bidrequest analysis is initiated. In some cases, the task manager caninitiate one or more tasks which are on external systems, such as anexternal campaign operations system 150. In some cases, the task managercan initiate a sequence of tasks, initiate parallel operation of tasksor both. In some cases, tasks may be selected or prioritized based onthe features of the bid request, such as the topic, or the mediaconsumption history of the entity representing the intended recipient ofthe advertising impression. In some cases, tasks can have an estimatedtime required for completion, and tasks may be selected or prioritizedbased on consideration of the estimated time required for completion andthe processing time limit. For example, tasks which are not expected togenerate a partial result before the processing time limit expires wouldnot be selected or initiated.

Referring to Step 440, a response is determined from one or more partialresults which are available before the processing time limit expires. Insome cases, partial results which are not made available to the responseconstructor 106 in time for consideration when constructing the responseare simply ignored. In some cases, the adaptive bidding system mayattempt to conserve resources by terminating tasks which are stilloperating when the processing time limit expires. In some cases, theadaptive bidding system may prevent the initiation of tasks which arequeued up for operation at the time the processing limit expires.

Referring to Step 450, a response is provided to the exchange. Theresponse can comprise a bid price or an indication that the adaptivebidding system has declined to bid on the advertising opportunityassociated with the bid request. In some cases, the response can alsoinclude an advertising creative, instructions to retrieve an advertisingcreative, instructions to customize an advertising creative orcombinations thereof.

In some embodiments of the invention, a processing time limit may bedetermined for each bid request, enabling the adaptive bidding system toremain responsive in spite of variations in network latencies acrossmultiple bid requests. Similarly, a bid analysis process may becustomized by the task manager for each bid request to take the bestadvantage of the available processing time by limiting low prioritytasks when a processing time limit is determined to be short anddesigning a more time consuming, and presumably more accurate, bidanalysis process when time permits.

The order of the steps in the foregoing described methods of theinvention are not intended to limit the invention; the steps may berearranged.
